Well she's my ex for far worse than that , but that's not a discussion for here. Lets just say that it was probably never the right thing to do(marrying her), it wasn't anything to do with "doing the right thing" just was never going to be right. Stuck it out for a long time, but anyways.
Funny story though, since I mentioned her penchant for spending a lot of money on clothes. After we were no longer together I was out and about with my gf at the time (R.I.P Debra) and I spotted my ex. We were at a mall so she was likely shopping for clothes, lol. She did not see me but I pointed her out to Debra who deadpanned "Why does she dress like an old lady?". Nearly pissed myself and choked on some food(we were in the food court).
